Embodiment 1

[0045] Such as figure 1 As shown, a five-hole power socket includes a base 1, a cover plate 2, and a power socket 4;

[0046] Such as figure 2 -3, the power socket 4 is composed of a three-hole socket 40 and a two-hole socket 44, a single-stage two-hole socket 441, a single-stage three-hole socket 401, and a power contact 43 form an independent single-stage The power supply socket 45; the ground wire socket 402 of the three-hole socket 40 is installed in the ground wire socket mounting seat 117 of the base 1, and the fixing method that the ground wire socket 402 often adopts is screw fixing and buckle fixing;

[0047] Such as figure 1 , Figure 4 As shown, the single-stage power socket 45 is symmetrically placed inside the groove 11 of the base; the above-mentioned base 1 cooperates with the cover 2 to form a rigid limiting system for fixing the power socket 4; The rigid limit system includes a line contact limit part and a surface contact limit part for limiting six degr...

Embodiment 2

[0053] Because the safety of the power socket is very important, on the basis of embodiment 1, embodiment 2 adds a safety door system. Such as Figure 7 As shown in —10, a safety door system 3 is provided at the two-hole socket 44 at the five-hole power socket; the safety door system 3 includes a compression spring 32 and a safety door sliding sleeve 31; one end of the compression spring 32 is installed on the safety door In the draw-in groove 311 of the sliding sleeve 31, the other end of the compression spring 32 is supported on the cover plate 2, and the safety door sliding sleeve 31 is installed in the guide box 22 of the cover plate 2 as a whole, and the outer wall of the safety door sliding sleeve 31 contacts the guide box 22. Inner wall; the safety door sliding sleeve 31 is provided with a guide groove 312, and the guide groove 312 is installed on the guide rib 12 of the base 1; the upper surface of the safety door sliding sleeve 31 is provided with a groove for prevent...

Embodiment 3

[0057] On the basis of Example 2, such as Figure 12 As shown, the line contact limiting part also includes two thimbles II 24 arranged on the cover plate 2 to push against the upper surface 451 of the single-stage power socket 45 near the three-hole socket 40 .

[0058] In the actual working process, the three-hole external power plug is inserted into the three-hole socket 40, and after use, the three-hole external power plug is manually pulled out. When pulling out the three-hole external power plug, a moment will be generated with the power contact 43 as the fulcrum and the single-stage three-hole socket 401 as the stress point. Since the formula of the torque is: M=F L (moment=forceⅹdistance); the upper surface 451 of the single-stage power socket 45 close to the three-hole socket 40 is supported by the two thimbles II 24 arranged on the cover plate 2 On, the distance from the force point to the fulcrum is shortened, thereby reducing the moment.

Abstract

The invention discloses a five-hole power socket, which is characterized by comprising a base, a cover plate and a power plug bush, wherein the power plug bush consists of a three-hole plug bush and a two-hole plug bush; a single-stage two-hole plug bush, a single-stage three-hole plug bush and a power contact constitute an independent single-stage power plug bush; a ground wire plug bush of the three-hole plug bush is mounted in a ground wire plug bush mounting seat of the base; the single-stage power plug bushes are symmetrically arranged inside a base groove; and the base and the cover plate are matched with each other to form a rigid spacing system for fixing the power plug bushes. According to the invention, line contact spacing components and surface contact spacing components for limiting six degrees of freedom of a power plug bush space are adopted for performing rigid location on the power plug bushes, and the five-hole power socket can also solve the problems that a traditional power plug bush consumes a large amount of materials and is poor in heat dissipating effect and short in service life. According to the invention, local deformation resulting from mutual interference of the three-hole plug bush and the two-hole plug bush can be prevented in use of the five-hole power socket.

Description

technical field [0001] The invention relates to a socket for household and similar fixed electrical devices, in particular to a five-hole power socket. Background technique [0002] According to information from the Fire Department of the Ministry of Public Security, electrical fires in residential buildings rank first. One of the reasons is: the safety of residential power outlets is not perfect; consumers' lack of electrical knowledge. [0003] Power socket refers to the device that is used to connect the alternating current that commercial power provides, makes household appliances and portable small equipment energized. The power socket is a female connector with a slot or a concave hole, which is used to insert a rod-shaped or copper plate-shaped protruding power plug to conduct electricity to an electrical appliance through the plug. [0004] To put it simply, the five-hole socket is a two-prong and one three-prong power socket. The five-hole socket can make more...
